Test Principle of the ID-Vit® Vitamin B1 Direct MTP Assay

The whole blood samples are pre-treated and diluted with a buffer mixture and then transferred into the wells of a microtiter plate coated with Lactobacillus fermentum. The addition of vitamin B1 in either standards or samples gives a vitamin B1-dependent growth response until vitamin B1 is consumed.

After incubation at 37 °C for 48 hours, the growth of Lactobacillus fermentum is measured turbidimetrically at 610–630 nm (alternatively at 540–550 nm) in an ELISA reader and compared to a standard curve generated from the dilution series. The amount of vitamin B1 is directly proportional to the turbidity.
